From Popular Science.

If you lived in the 1920s, you might have found a pamphlet advertising “the greatest therapeutic force known to mankind.” Radithor was a tiny bottle of clear, colorless water that claimed to cure acne, anemia, heart disease, poison ivy, impotence, asthma, and any other malady you could imagine.

There was only one side effect: DEATH.

So, why did 1920s Americans go gaga for radioactive water? Well, it’s complicated.
